MultiFamily Property zoned as single family

[Mariana Hernandez]

We have been under contract for a Four-plex  but after the appraiser came out to see property he mentioned house was never zoned for multi family. It has all utilities separated, as well as entrances, etc. Now lender is saying it can't fund the deal because zoning is not correct. Our agent is saying we could try to get funding as a single family and then get it switched afterwards. 

Any ideas on how to fix this?
